Final Countdown Deck

Win Condition

Currently this deck type uses the card "Final Countdown" in order to win. The overall desire is to stall the game for 20 turns total (10 of your turns, and 10 of your opponent's turns).

The deck can possibly have alternate win conditions, for example if you're playing "Metaion, the Time Lord", "Lava Golem", and/or "Marshmallon", there's the possibility of doing enough damage by card effects to win as well.

Weaknesses

This can be a huge threat to this deck if used properly, if a player sets this card then waits until the end phase to activate it, then it can be the kiss of death to any inexperienced player of this deck. If this strategy is used it can end the game in one turn unless they have a card in hand to end the battle phase.

This can possibly end the game for anyone using a final countdown deck, as this card can end the game in three turns. It's highly recommended a player plays "Dark Hole" or "Metaion, the Time Lord" in their main deck to counter this. "Lava Golem" can be used as well, but if it's the only monster on the field it will have no use.

Hand Control Decks

These are the biggest threat to this deck type, as this deck relies very heavily on maintaining card advantage. If you opponent makes you discard more than a few cards from your hand, you'll be left at a serious disadvantage. Decks such as Dark World and X-Saber are extremely bad match-ups for this deck.

Shi En negates a spell/trap every turn, which will leave you at a -1 card advantage every turn he activates. Cards such as "Metaion, the Time Lord" and "Lava Golem" counter this card, and are both very playable in the main deck.

Some versions of this deck lose very easily because of this card alone. Having "Mystical Space Typhoon" in your side deck will help stop this. You can also lessen this weakness heavily by playing a mix of spells, traps, and monsters, rather than all traps.
